Kevin,As always, I put this out for informational purposes only. I have seen a few NDE accounts which indeed mention two lakes-of-fire. The first one is in the current, temporary Hell (Sheol) and is the current fate of some of the damned. The second lake is Gehenna, a bigger LOF that will, after final judgment, accept Sheol and everything/one in it. The first one is on the Earth, well actually in the Earth, at its center. I don't know where the second one is.
The best place to start is with the Scriptures and not near-death experiences, which are so subjective.
By the way, Sheol is the place in the OT for life after death for both believers and non-believers. The NT equivalent is Hades.
In the 'Hell Fire' thread, I presented this biblical evidence of what happens at death:
We learn from the Scriptures that there are three dimension to death. These are:- Physical death. This is the separation of the soul from the body and this is the penalty of sin (see Gen. 2:17; 3:19; Num 16:29; 27:3; John 8:44; Rom 5:12, 14, 16, 17; 1 Peter 4:6).
- Spiritual death. This is the separation of the soul from God which is a penalty from the fall into sin in the Garden of Eden (see Gen 2:17; Rom 5:21; Eph 2:1, 5; Luke 15:32; John 5:24; 8:51).
- Eternal death (the second death). This is the completion of spiritual death, the eternal separation of the soul from God which is accompanied by eternal punishment (see Matt 10:28; 25:41; 2 Thess 1:9; Heb 10:31; Rev 14:11). [this outline from Henry Thiessen 1949:271-272]
Is there a conscious existence after death? Luke 16:19-31 ESV teaches that there is - as well as other portions of the NT.
